PWC webcam error: -28 fix

If your Philips webcam (PWC) is not working (using xawtv for example) and your /var/log/syslog shows a message like this:

pwc: isoc_init() submit_urb 0 failed with error -28

Then install setpwc and use the following command:

setpwc -c 3

That's all...

Update: this does not work with mencoder :-(
